Steal what information?
The earliest that you will be able to file 2021 tax will probably be late January 2022. The exact date will not be known until sometime in January - it depends on the IRS and if there are any late tax law changes.
Apply for an IP PIN now and they will mail it to you in January... this will keep anyone from filing a return using your SS#. https://www.irs.gov/identity-theft-fraud-scams/get-an-identity-protection-pin
